While the concept is good, we felt cheated. You are not allowed to take pictures in the house. The whole idea is to showcase the uniqueness of the upside down house but unfortunately when you are not allowed to take pictures then is defeats the idea. They should at least inform visitors that cameras are not allowed in the house. You are only told upon entering the house and that too forcefully reminded of the consequences if found taking pictures. My recommendation - there are many other such places in Malaysia, visit those places where pictures are allowed to be taken. A BIG thumbs down for this place.
